COYOTE (Call Off Your Old Tired Ethics) was founded in 1973 as a union and advocacy group for prostitutes and others involved in the sex industry. Founded by Margo St. James, a former prostitute and madam, the group advocates for the decriminalization of prostitution as well as providing education to the public, expert testimony in legal cases and support and services to those involved in sex work. This button, from the mid-70s shortly after COYOTE was founded, features one of the group’s tag lines, “A Loose Woman’s Organization.” COYOTE is still active today with chapters in multiple states.
